ZF-5193: Implement and Test Zend_Soap_Wsdl_Parser classes
The SOAP Wsdl Parser is needed for 2 reasons:
- if a well tested parser exists, one can switch all wsdl and autodiscover unittests to using the parser instead of matching the complete xml string.
- for Zend_Tool a build Provider to create SOAP Clients from WSDL definition files would be a great asset.
There are already classes Zend_Soap_Wsdl_Parser* stuff, but they are not really part of the current SOAP distribution.
